Wowsers waht a crazy two weeks. I have just crashed at the en d of each night. Anyway off to the topic. Just wanted to post the solid model technique we use to get better, closer contacts, quicker. Everybody looks for quicker. First we have three solid models; A. Mesial adjacent tooth and prep, with tissue completely removed and margin trimmed nicely, B. Distal adjacent tooth and prep, with tissue completely removed and margin trimmed nicely, C. Both Mesial and Distal adjacent teeth and prep, with tissue form carefully to mimic proper intra-oral formation. Models A. and B. are used as quick grind guides to get contacts seated very close very quickly. Model C. is used as the precision model, you can get the final contacts with just a quick touch of your bur, as well as correct contour for proper tissue management(this is generally a very revealing stage, as to how much tissue is generally impinged upon), and any finishing touches, i.e. perikymata, furcation indentations, etc. I will upload pictures of examples as soon as our camera gets back from the repair shop. Please comment if you have any questions.

I like it! This technique reminds me of finishing a gold crown with just one contact to worry about. We are already utilizing a solid model technique with just one model. I guess two more solid models won’t hurt. again I like it!
